Threats to Rare Plant Persistence

Abstract

Many plant populations and metapopulations all over the world are being threatened by a variety of factors (Semenova and van der Maarel 2000). in most cases, threats are associated with human actions of some sort (Lande 1998), which implies that we can often take action to remove or at least counter them. However, for many threats it is difficult (1) to understand how they ultimately affect the viability of specific plant populations or metapopulations, (2) to untangle their interaction with other threats, and (3) to come up with effective methods to alleviate them.
